As of January 1, 2017, new gun controls expanded the definition of “assault weapons” in California and required owners of all such guns to register them with the state government.

But now two inventors, Travis Klein and Bart McCurdy, have created a new method of taking down an AR-15 that they say will allow owners of said guns to legally avoid registering them with the state.

According to Law Officer.com, Klein and McCurdy’s invention allows AR-15 owners to quickly take down their rifles in order to switch out an empty magazine for a full one.

The newest laws in California were aimed at outlawing “bullet buttons” — special California-specific buttons which allowed AR-15 owners to eject empty magazines by using a sharp tool or bullet point. With such buttons outlawed, the only way to legally eject magazines in California is to break down the AR — to literally remove the rear pin and separate the upper receiver from the lower, and only then to remove the empty magazine.

The Patriot Pin allows AR-15 owners to do this quickly. A small “take down arm” affixes to the rear pin of the AR, allowing the person holding the gun to use his or her thumb to quickly remove the pin after the magazine is empty. With the pin removed, the upper receiver separates from the lower and an “ARMagLock” can then be pressed with the index finger, dropping the empty magazine.

The Patriot Pin website says, “The new [gun control] law states you must disassemble your rifle before you are able to release the magazine. By installing an ARMaglock, by definition, you are compliant under the new laws.”

The installation of the Patriot Pin and the ARMagLock require “no permanent modifications” to your AR-15.
